DSAEK and PK graft survival, endothelial cell density rates similar at 3 years

Descemet’s stripping automated endothelial keratoplasty and penetrating keratoplasty had similar graft survival and endothelial cell loss rates at 3 years, according to a study. The prospective clinical trial included 173 subjects who underwent DSAEK and 1,101 subjects who underwent PK. DSAEK was performed by two surgeons at two centers, and PK data were culled from the Cornea Donor Study and the Specular Microscopy Ancillary Study.
